UPRlGHT-PlANO-ACTION FRAME.

SPECIFICATION forming part of Letters Patent No. 338,918, dated March 30, 1886.

Application filed May 19. 1884.

To all whom it may concern:

Be it known that we, WILLIAM BOURNE and CHARLES E. BOURNE, both of Boston, in the county of Suffolk and Commonwealth of Massachusetts, and citizens of the United States, have invented a new and useful Improvement in Upright Pianos, of which the following is a specification.

Our invention relates to an improvement IO in the construction and arrangement of the brackets by which the action-frame is supported; and it consists in making the lower part of each bracket with two spreading branches or legs, forming a broad base, which gives it a firm support, and attaching the bracket so constructed rigidly to the bottom of the instrument, thus avoiding the neces sity of fastening the actionframe at the top to the piano-case or the wrest-plank. By this means the action-frame is more steadily supported than it is when constructed in the usual manner, and it can be more readily removed from the case and with less danger ofinjury to itself and the adjoining parts. The tone of the instrument is also improved.

In the accompanying drawings, Figure 1 is a side view of our improved bracket with the action attached, and Fig. 2 is a front View of the same.

A is the bracket, made of cast-iron or other suitable material, to which the cross-rails of the action-frame are attached in the usual Serial No. 131,969. (No model.)

manner. The lower end of the bracket is divided, forming two legs, B and C, the feet of which are sufliciently far apart to furnish the 3 5 action-frame with a firm lateral support.

Dis the bottom of the instrument, on which the brackets A rest. The position of the upper part of the bracket and the action thereto attached relative to the strings is regulated 0 by means of the adjusting-screws E, on which one or both of the bracket-legs B C rest.

F is a bolt fixed in the bottom of the piano and projecting through an orifice in the horizontal portion of the leg C. On the upper 5 end of this bolt is cut a thread, on which turns the nut G, by means of which the bracket is held firmly to the bottom of the piano.

What we claim, and desire to secure by Letters Patent, is

1. In an upright piano, the action brackets A, supported by legs BC, in combination with the bolt F, nut G, and adjustingscrews E, substantially as and for the purpose described.

2. In an upright piano, the action-brackets A, supported by legs B C, resting upon the bottom of the instrument, in combination with the bolt F and nut G, substantially as and for the purpose described.
